Detailed Description

template<unsigned D, typename T, typename S>
class olb::AnalyticalCuboidwiseConst< D, T, S >

Returns a constant value on every cuboids.

The cuboid decomposition is independent of the simulation geometry. SuperStructure etc. are only needed because our functor stucture requires this. Scaling of this functor is problematic because of a primitive underlying search algorithm. Hence, this functor should not be applied in any performance critical context.
